47、 A downlink adjacent channel refers to transmission in downlink direction using any one of the adjacent DSRC downlink channels at a distance of 5 MHz, i.e. in the channel at the next upper or lower centre frequency. An uplink adjacent channel refers to transmission in uplink direction using any one
48、of the uplink communication channels related to a centre frequency at a distance of 5 MHz relative to the own downlink centre frequency. bit: acronym for “binary digit“ which can have one out of two possible values, e.g. 0/1 or +1/-1 or low/high bit rate: in a bit stream, the number of bits occurrin
49、g per unit time, usually expressed in bits per second bore sight: direction of maximum radiation of a directional antenna NOTE: If bore sight can not be determined unambiguously, then bore sight may be declared by the provider. carrier frequency: frequency fTxto which the RSU transmitter is tuned NOTE: In DSRC, the carrier frequency is in the centre of a channel, see table 2 of the present document. carrier signal or carrier: harmonic signal whose nominal single frequency fTxcan vary within a range specified by the carrier frequency tol
